ABSTRACT The invention relates to thermoplastic polyurethane blends containing at least one thermoplastic polyurethane and at least one copolymer, the copolymer derivedfrom at least 5 weight percent of an N-vinyl lactam monomer unit. Blends of the invention generally are compatible or miscible, and many exhibit clarity and other physical properties, such as tensile modulus, distortion resistance and impact resistance, which are improved over the properties of the thermoplastic polyurethane component of the blend or of thermoplastic polyurethanes blends in the art.
